Abstract

ABSTRACT Purpose To identify the development of initial auditory skills in children with unilateral and bilateral cochlear implant during the first year of use. Methods Retrospective longitudinal study of medical records of children who received cochlear implant under the age of four, separated into two groups. The first, composed of children implanted unilaterally and the second, by children implanted and simultaneously. Data on the IT-MAIS scale (Infant-Toddler Meaningful Auditory Integration Scale) were collected before surgery and three months, six months and one year after surgery. These results were compared with the existing Clinical Markers. In addition, the family’s classification was noted, according to the Family Involvement Assessment Scale. Results The data of 29 children with bilateral cochlear implant and 30 children with unilateral cochlear implant were evaluated. The IT-MAIS score of the two groups was similar to the Clinical Markers. Regarding the Family Involvement Assessment Scale, there was a difference, showing that families in the bilateral group were more involved. Conclusion In the first year of use of the cochlear implant, the development of children implanted bilaterally did not differ from the development of children implanted unilaterally, suggesting that initial auditory skills are likely to develop with unilateral auditory input.
